Abstract

A pill dispensing apparatus includes a container capable of holding a plurality of pills of a type of medication. A bottom wall of the container defines an opening. The apparatus includes a housing defining an interior space and having a top wall defining an aperture, the aperture and bottom wall opening having complementary configurations. The container may be positioned on the housing such that the opening and aperture are aligned. A dispensing assembly mounted within the housing includes a pair of wheels positioned so as to convey a single pill from the container therebetween and to an outlet when the wheels are rotated in opposing directions. A motor energized by a control unit according to previously entered dosage data causes the wheels to rotate until a photoelectric sensor detects that the pill has been dispensed. In another embodiment, a knob connected to the wheels allows manual wheel rotation.
